CHAPTER XXIV

THE GREEN RUST FACTORY

Stanford Beale spent a thoughtful three minutes in the darkness of the

cellar passage to which Hilda Glaum had led him and then he began a

careful search of his pockets. He carried a little silver cigar-lighter,

which had fortunately been charged with petrol that afternoon, and this

afforded him a beam of adequate means to take note of his surroundings.

The space between the two locked doors was ten feet, the width of the

passage three, the height about seven feet. The roof, as he had already

noted, was vaulted. Now he saw that along the centre ran a strip of

beading. There had evidently been an electric light installation here,

probably before the new owners took possession, for at intervals was a

socket for an electric bulb. The new occupants had covered these and the

rest of the wall with whitewash, and yet the beading and the electric

fittings looked comparatively new. One wall, that on his left as he had

come in, revealed nothing under his close inspection, but on the right

wall, midway between the two doors, there had been a notice painted in

white letters on a black background, and this showed faintly through the

thick coating of distemper which had been applied. He damped a

handkerchief with his tongue and rubbed away some of the whitewash

where the letters were least legible and read:

AID

LTER.

------

ULANCE &

T AID.

This was evidently half an inscription which had been cut off exactly in

the middle. To the left there was no sign of lettering. He puzzled the

letters for a few moments before he came to an understanding.

"Air-raid shelter. Ambulance and first aid!" he read.

So that explained the new electric fittings. It was one of those

underground cellars which had been ferreted out by the Municipality or

the Government for the shelter of the people in the neighbourhood during

air-raids in the Great War. Evidently there was extensive accommodation

here, since this was also an ambulance post. Faintly discernible beneath

the letters was a painted white hand which pointed downward. What had

happened to the other half of the inscription? Obviously it had been

painted on the door leading into the first-aid room and as obviously

that door had been removed and had been bricked up. In the light of this

discovery he made a more careful inspection of the wall to the left. For

the space of four feet the brickwork was new. He tapped it. It sounded

hollow. Pressing his back against the opposite wall to give him leverage

he put his foot against the new brickwork and pushed.

He knew that the class of workmanship which was put into this kind of

job was not of the best, that only one layer of brick was applied, and

it was a mechanical fact that pressure applied to the centre of new work

would produce a collapse.

At the first push he felt the wall sag. Releasing his pressure it came

back. This time he put both feet against the wall and bracing his

shoulders he put every ounce of strength in his body into a mighty

heave. The next second he was lying on his back. The greater part of the

wall had collapsed. He was curious enough to examine the work he had

demolished. It had evidently been done by amateurs, and the whitewash

which had been thickly applied to the passage was explained.

A current of fresh air came to meet him as he stepped gingerly across

the debris. A flight of six stone steps led down to a small room

containing a sink and a water supply, two camp beds which had evidently

been part of the ambulance equipment and which the new owners had not

thought necessary to remove, and a broken chair. The room was still

littered with the paraphernalia of first-aid. He found odd ends of

bandages, empty medicine bottles and a broken glass measure on the shelf

above the sink.

What interested him more was a door which he had not dared to hope he

would find. It was bolted on his side, and when he had slid this back he

discovered to his relief that it was not locked. He opened it carefully,

first extinguishing his light. Beyond the door was darkness and he

snapped back the light again. The room led to another, likewise empty.

There were a number of shelves, a few old wine-bins, a score of empty

bottles, but nothing else. At the far corner was yet another door, also

bolted on the inside. Evidently van Heerden did not intend this part of

the vault to be used.

He looked at the lock and found it was broken. He must be approaching

the main workroom in this new factory, and it was necessary to proceed

with caution. He took out his revolver, spun the cylinder and thrust it

under his waistcoat, the butt ready to his hand. The drawing of the

bolts was a long business. He could not afford to risk detection at this

hour, and could only move them by a fraction of an inch at a time.

Presently his work was done and he pulled the door cautiously.

Instantly there appeared between door and jamb a bright green line of

light. He dare not move it any farther, for he heard now the shuffle of

feet, and occasionally the sound of hollow voices, muffled and

indistinguishable. In that light the opening of the door would be seen,

perhaps by a dozen pair of eyes. For all he knew every man in that room

might be facing his way. He had expected to hear the noise of machinery,

but beyond the strangled voices, occasionally the click of glass against

glass and the shuff-shuff-shuff of slippered feet crossing the floor, he

heard nothing.

He pulled the door another quarter of an inch and glued his eye to the

crack. At this angle he could only see one of the walls of the big vault

and the end of a long vapour-lamp which stood in one of the cornices and

which supplied the ghastly light. But presently he saw something which

filled him with hope. Against the wall was a high shadow which even the

overhead lamp did not wholly neutralize. It was an irregular shadow such

as a stack of boxes might make, and it occurred to him that perhaps

beyond his range of vision there was a barricade of empty cases which

hid the door from the rest of the room.

He spent nearly three-quarters of an hour taking a bearing based upon

the problematical position of the lights, the height and density of the

box screen and then boldly and rapidly opened the door, stepped through

and closed it behind him. His calculations had been accurate. He found

himself in a room, the extent of which he could only conjecture. What,

however, interested him mostly was the accuracy of his calculation that

the door was hidden. An "L"-shaped stack of crates was piled within two

feet of the ceiling, and formed a little lobby to anybody entering the

vault the way Beale had come. They were stacked neatly and methodically,

and with the exception of two larger packing-cases which formed the

"corner stone" the barrier was made of a large number of small boxes

about ten inches square.

There was a small step-ladder, evidently used by the person whose

business it was to keep this stack in order. Beale lifted it

noiselessly, planted it against the corner and mounted cautiously.

He saw a large, broad chamber, its groined roof supported by six squat

stone pillars. Light came not only from mercurial lamps affixed to the

ceiling, but from others suspended above the three rows of benches

which ran the length of the room.

Mercurial lamps do not give a green light, as he knew, but a violet

light, and the green effect was produced by shades of something which

Beale thought was yellow silk, but which he afterwards discovered was

tinted mica.

At intervals along the benches sat white-clad figures, their faces

hidden behind rubber masks, their hands covered with gloves. In front of

each man was a small microscope under a glass shade, a pair of balances

and a rack filled with shallow porcelain trays. Evidently the work on

which they were engaged did not endanger their eyesight, for the

eye-pieces in the masks were innocent of protective covering, a

circumstance which added to the hideous animal-like appearance of the

men. They all looked alike in their uniform garb, but one figure alone

Beale recognized. There was no mistaking the stumpy form and the big

head of the Herr Professor, whose appearance in Oliva Cresswell's room

had so terrified that young lady.

He had expected to see him, for he knew that this old German,

poverty-stricken and ill-favoured, had been roped in by van Heerden, and

Beale, who pitied the old man, had been engaged for a fortnight in

trying to worm from the ex-professor of chemistry at the University of

Heidelberg the location of van Heerden's secret laboratory. His efforts

had been unsuccessful. There was a streak of loyalty in the old man,

which had excited an irritable admiration in the detective but had

produced nothing more.

Beale's eyes followed the benches and took in every detail. Some of the

men were evidently engaged in tests, and remained all the time with

their eyes glued to their microscopes. Others were looking into their

porcelain trays and stirring the contents with glass rods, now and again

transferring something to a glass slide which was placed on the

microscope and earnestly examined.

Beale was conscious of a faint musty odour permeating the air, an

indescribable earthy smell with a tang to it which made the delicate

membrane of the nostrils smart and ache. He tied his handkerchief over

his nose and mouth before he took another peep. Only part of the room

was visible from his post of observation. What was going on immediately

beneath the far side of the screen he could only conjecture. But he saw

enough to convince him that this was the principal factory, from whence

van Heerden was distilling the poison with which he planned humanity's

death.

Some of the workers were filling and sealing small test-tubes with the

contents of dishes. These tubes were extraordinarily delicate of

structure, and Beale saw at least three crumble and shiver in the hands

of the fillers.

Every bench held a hundred or so of these tubes and a covered gas-jet

for heating the wax. The work went on methodically, with very little

conversation between the masked figures (he saw that the masks covered

the heads of the chemists so that not a vestige of hair showed), and

only occasionally did one of them leave his seat and disappear through a

door at the far end of the room, which apparently led to a canteen.

Evidently the fumes against which they were protected were not virulent,

for some of the men stripped their masks as soon as they left their

benches.

For half an hour he watched, and in the course of that time saw the

process of filling the small boxes which formed his barrier and

hiding-place with the sealed tubes. He observed the care with which the

fragile tubes were placed in their beds of cotton wool, and had a

glimpse of the lined interior of one of the boxes. He was on the point

of lifting down a box to make a more thorough examination when he heard

a quavering voice beneath him.

"What you do here--eh?"

Under the step-ladder was one of the workers who had slipped noiselessly

round the corner of the pile and now stood, grotesque and menacing, his

uncovered eyes glowering at the intruder, the black barrel of his

Browning pistol covering the detective's heart.

"Don't shoot, colonel," said Beale softly. "I'll come down."
